WILLIAM J. McGEHE, OF BUSHNELL, ILLINOIS.

HAND-CULTIVATOR.

T 0 all whomtt may concern.

Be it known that I, I/VILLIAM J. McGEHE, a citizen of the United States, residing at Bushnell, Illinois, have invented certain new and useful Improvements in Hand-Cultivators, of which the following is a specification.

My invention relates to hand or garden plows and cultivators, and has for its object the production of a plow or cultivator in which the shovels or teeth may readily be interchangeable and easily adjustable, both as to the depth and as to the angle in relation to the vertical plane of the standard.

ith these objects in view, my invention consists of the construction hereinafter described and more particularly pointed out in the claims.

Referring to the accompanying drawings,Figure 1 is a plow embodying my in- Fig. 2 is a side view of the standard and shank with one side partially broken away to show the spring plate. Fig. 3 is a longitudinal section of Fig. 2.

In these drawings, A is the frame of a wheeled hand plow of ordinary construction. Rigidlysecured to the frame A at a is the hollow standard B, preferably rectangular in cross-section and adapted to receive the shank O which slides freely therein and carries the plow shovel c. A set screw 0 is provided to lock the shank in its adjusted posi tion within the standard. This shank C is of such a width that it fits snugly between the side walls of the hollow standard, but its depth is considerably less than the distance between the front and rear walls of the standard, thus allowing it to move freely therein. The rear wall of the hollow standard may be cut away as shown at b to allow a greater freedom of movement to the shank and when this is done a strip or bar 0 is secured across the open side to carry the set screw 0. In order to adjust the shank in the Specification of Letters Patent.

Application filed June 17. 1907. Serial No. 379.464.

Patented. Dec. 3, 1907.

desired vertical plane I provide a set screw (1 in the front wall of the hollow standard and at some, distance above the set screw in the rear wall thereof. Within the standard and secured to the front wall near the bottom thereof is a spring or pivoted late D whichextends beyond the set screw and is adapted to be engaged thereby and the u per end of the same forced away from the Weill.

From the foregoing description it will be apparent that to adjust the plow shovel the shank is pushed up into the hollow standard to the proper height and the plate D forced against the shank until it has reached the desired angle in relation to the standard, and the set screw 0 turned down to lock the same in the adjusted position.

Although I have described the standard B as rectangular in cross section, it is obvious that both it and the shank may be made of any shape which will permit of the necessary motion, and that any suitable locking device may be substituted for the set screws 0 and d.

What I claim is In a device of the class described, a hollow standard, a blade carrying shank located in the hollow standard and fitting between the sides thereof but of less thickness than the distance between the inner faces of the front and rear walls of the standard, a set screw passing through the rear wall of the standard near the lower end thereof, and impinging against the rear side of the shank, a second set screw passing through the front wall above the line of the first screw, and a leaf spring interposed between the shank and front wall of the standard, substantially as described. 7

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM J. MOGEHE.
